On Windows 7, I have an application that can't run in 64 bit. How do I invoke wow64 manually? Compatibility mode does not work, nor does pasting it into C:/Program Files (x86)/.

You cannot. If the .exe file is marked as "x64", Windows will run it in 64-bit mode. If the .exe is marked as "x32", it will be run in 32-bit mode using wow64. Having "an application that can't run in 64-bit" doesn't make much sense, as 32-bit programs are never run directly in 64-bit mode.

A more specific problem description than just "can't run" would be helpful.

When I run the executable it pops up with the following error: [Content] The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher. [OK] – apscience Aug 21 '11 at 12:04
which executible is that? – Sathya Aug 21 '11 at 12:18
What kind of executable is it? x64, 32-bit x86, or perhaps 16-bit? (Note that 16-bit programs cannot be run directly on a 64-bit OS.) – grawity Aug 21 '11 at 12:23
It could be that the EXE file is broken. Try to get the same file again. – sinni800 Aug 21 '11 at 12:46
I had the same issue with a game called Rampart. It's an old Midway Arcade Game. Someone had made a version of it that looks like the arcade. I thought the same, 32 bit possibly. But the game was made in 1994. After I read the post about it possibly being a 16 bit exe; well, "Occums' Razor" can fill the rest. Cheers! – user163501 Oct 6 '12 at 20:08
